DANIEL HAYS, OF GLOVERSVILLE, NEV YORK.

AFFWUHTU S FO R MAM U FACTU Bibl@ LEATH Elfi` SPECIFICATION forming part of Letters Patent No. 595,304, dated December 14, 1897.

Application filed June 19, 1897. Serial No. 641,496. (No model.)

Be it known that l, DANIEL llAYs, residing at Gloversville, in the county of Fulton and State of New York, haveinvented a new and useful Apparatus for the Manufacture of Leather, of which the following is a specification.

My invention relates to an apparatus for fulling and drying hides and skins, the general object of my invention being to provide improved means whereby such operation of fulling and drying is expedited, cheapened, and simplified.

The special object of myinvention is to provide improved means for forcing air through or among the hides or skins while contained within a stock or vat while being subjected to the beatingl or hammering operation.

My invention consists in a stock or vat for hides having beaters or hammers operating therein through an opening in the top, and aprons attached to the edges of the opening and depending into the stock, suitable airpipes leading through the top or cover being also provided.

My invention further consists in the improved construction, arrangement, and combination of parts hereinafter fully described, and afterward specifically pointed out in the claims.

ln order to enable others skilled in the art to which my invention most nearly appertains to make and use the same, l will now proceed to describe its construction and operation, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 is a perspective view of my improved apparatus in position for practical operation. Fig. 2 is a central longitudinal section through the same, the beaters being shown in side elevation and the upper portion of the apparatus broken away. Fig. 3 is a transverse vertical section through the same on the plane indicated by the broken line 3 3 of Fig. 2.

Like letters of reference mark the same parts wherever they occur in the different ligures of the drawings.

Referring to the drawings by letters, A is the stock or vat, which is substantially the same in general shape and size as the stocks or vats now in use, and working in said stock or vat are the beaters or hammers B, said beaters or hammers being suspended upon a shaft C, which is supported by standards D, projecting upwardly from the sides of the stock or vat. The beaters or hammers are also provided with the depending portions B, to which pitmen E are attached.

Air from any suitable blower, after passing through any suitable heating apparatus for varying its temperature, is forced into the stock through the medium of a large pipe F above the blower7 having extending downwardly therefrom in inclined directions an indeiinite number Of laterals G, each communicating with a head ll, provided with a series of downwardly-extending tubes I, leading to perforations or holes in the top of the stock A, said holes being arranged or formed in all portions of the top, whereby the air forced through the series of pipesand tubes before mentioned will be forced among and through the hides or skins within the stock as the skins are beaten and turned.

In order to provide for the swinging of the beaters or hammers B, longitudinally arranged openings .l are provided in the top of the stock or vat, and to prevent the air being forced into the vat from escaping through said openings I provide leather aprons K to close said openings, said aprons being hung from the edges of the openings into the vat or stock on each side of the hammers. lVhen the beater is in a vertical position at about the centerof its movement, the leather aprons K will appear as shown in Fig. 2. At each end of the stock or vat I provide means for opening the top thereof to insert and remove the skins, such means consisting of upright boards L and top boards or doors M, the boards L forming a portion of the sides of the stock when in position and the doors M forming a portion of the top thereof, one of the boards L being removed as the stock is illustrated in Fig. 1 and one of the doors M being raised. Vhen the openings are closed, the boards L are held in place by means of pins N, which when not in use are suspended by cords O.

lVhen the beater is moved toward either side, it crowds the material in that side, so that there is a tendency for the air to rush IOO up and out of the opening J. This forces the apron on that side against the beater, thus impeding the escape of the air.

The advantages attending the use of my invention Will be apparent from the foregoing description, it being obvious that I have provided an exceedingly cheap, simple, and efficient means for fulling and drying skins, and While I have illustrated and described the best means now known to me for carrying out my invention I Wish it to be understood that I do not restrict myself to the exact details of construction shown and described, but hold that any slight changes or variations, such as might suggest themselves to the ordinary mechanic, would clearly fall Within the limit and scope of my invention.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. In an apparatus for manufacturing leather, a stationary stock or vat having beaters or hammers operating therein, a top or cover fitted upon said stock or vat and having an opening at the center to permit the movement of the beaters or hammers, the aprons attached to the edges of said opening and depending into the stock, and the airpipes leading into the stock or vat through the top or cover, substantially as described.

2. ln an apparatus for manufacturing leather, a stationary stock or vat having beaters or hammers operating therein, a top or cover fitted upon said stock or vat and having an opening at the center to permit the movement of the beaters or hammers, said cover o r top having one or more hinged lids or portions, the aprons attached to the edges of the central opening and depending into the stock, and the air-pipes leading into the stock or vat through the top or cover, substantially as described.
